It is very easy to use, I love that my team can just log in from anywhere using our own web browsers! The only thing it lacks are some more features like time zone settings or other countries/regions (such as Russia).
We're looking into this now so hopefully we will be able get all these missing functions soon! If you don't know how to code at least basic Javascript then there's no point of trying out their free trial version because most things need coding knowledge which they do not provide yet. Their documentation makes everything clear but also provides examples if needed - great support even after hours until late nights when people aren’t around :D.
